Published: July 2, 2024

The impedance matching of absorbers is a vital factor affecting their microwave absorption (MA) properties. In this work, we controllably synthesized Material Institute Lavoisier 88C (MIL-88C) with varying aspect ratios (AR) as precursor by regulating oil bath conditions, followed one-step thermal decomposition to obtain carbon-coated iron-based composites. Modifying the MIL-88C (Fe) preparation such molar ratio between metal ions and organic ligands (M/O), temperature, time, influenced phases, graphitization degree, AR derivatives, enabling low filler loading, achieving well-matched impedance, ensuring outstanding MA MOF-derivatives 2 (MD

Published: March 22, 2024

Abstract MXene, a highly regarded material, has garnered significant attention within the electromagnetic wave (EMW) absorption field. However, practical application of MXene is limited in harsh environments. Herein, magic technique strategy intercalation growth nucleation engineering employed to prepare multifunctional MXene‐based EMW materials. By regularly introducing different metal ions between layers an ultrathin absorber can be achieved by annealing after reacting specific positions. The synthesized MCFC‐69‐8 shows hydrophobicity properties and exhibits large charge‐transfer resistance 18112 Ω cm 2 with low corrosion rate rate, indicating good anti‐corrosion property. Through applying series mathematical methods, 25% relaxation polarization loss 75% conduction loss, its time linked type resulting effective bandwidth (EAB) 4.9 GHz ultra‐thin optimal matching thickness 1.48 mm. Finally, built using CST attain ultrabroad EAB covering 2–18 GHz. This not only simplifies process but also achieves high‐performance absorber, providing valuable perception for realizing thinner absorbers future.

Abstract Interface design has enormous potential for the enhancement of interfacial polarization and microwave absorption properties. However, construction interfaces is always limited in components a single dimension. Developing systematic strategies to customize multidimensional fully utilize advantages low‐dimensional materials remains challenging. Two‐dimensional transition metal dichalcogenides (TMDCs) have garnered significant attention owing their distinctive electrical conductivity exceptional effects. In this study, series hollow TMDCs@C fibers are synthesized via sacrificial template CdS confined growth TMDCs embedded fibers. The complex permittivity can be adjusted by tuning content templates. Importantly, contribute elevating performance. Among fibers, minimum reflection loss (RL min ) MoS 2 @C reach −52.0 dB at thickness 2.5 mm, with broad effective bandwidth 4.56 GHz 2.0 mm.
